Switch VLAN Probe Utility

The VLAN probe function utilizes DHCP client on the switch to check for and display IP connectivity on a specified VLAN.

Note

If the VLAN selected to perform a VLAN probe already has a static IP address or is DHCP enabled, the VLAN probe will be skipped for that specific VLAN.

Use this task to locate available VLANs for devices in a complex network with multiple VLANs. VLAN probe for a Switch Engine device can also be triggered through the topology map.

Verify the VLAN probe results and status of VLAN for seleted device.

Go to Manage > Devices select the associated device.
Select Utilities > Tools > Switch VLAN Probe.
Enter the start and end of a range of VLAN IDs to probe.
You can enter up to five ranges separated by commas, up to a total range of 12, however, range numbers cannot overlap. For example, 1,2-7,8,9-12.
(Optional) Add a timeout from 5 to 60 seconds to specify how long to wait for a reply from each probe.
Select Start to start a probe.
Select Stop to stop a probe before it is complete.
Select Clear to clear entries for a probe.

When the VLAN probe is complete, a table shows the host name, MAC address, available VLANs, unavailable VLANs, and their status.
